This can happen if the Uemis is not correctly connected, but the user
still has the path set (as default DC most likely) and tries to start a

This may seem like a really odd change - but with this change the Qt tools
can correctly parse the C files (and qt-gui.cpp) and get the context for
the translatable strings right.
It's not super-pretty (I'll admit that _("string literal") is much easier
on the eye than translate("gettextFromC", "string literal") ) but I think
this will be the price of success.

Most of the warnings are IMHO false positives:
e.g.: an enum variable is initialized in a switch statement that has a case for
each possible enum value - yet gcc 4.8 warns that it could be used
uninitialized;
or: two variables are initialized together in the code - second one of them
is previously initialized to -1 at declaration time, both are initialized
in an if (second one == -1) clause - so they are guaranteed to both be
initialized...
I did not "fix" those as the code is actually correct.
But there are three spots where it catches things that could indeed go wrong
(with odd input data in one of them).
This commit also adds a check to only call g_type_init() for older versions of
glib as in newer ones it is deprecated.

This is simplistic & brute force: any function that touches Gtk related

A couple of these could clearly cause a crash just like the one fixed by
commit 00865f5a1e1a ("equipment.c: Fix potential buffer overflow in
size_data_funct()").
One would append user input to fixed length buffer without checking.
We were hardcoding the (correct) max path length in macos.c - replaced by
the actual OS constant.
But the vast majority are just extremely generous guesses how long
localized strings could possibly be.
Yes, this commit is likely leaning towards overkill. But we have now been
bitten by buffer overflow crashes twice that were caused by localization,
so I tried to go through all of the code and identify every possible
buffer that could be affected by this.

The Uemis SDA returns the data for each dive from several different
databases. And oddly, the getDive data uses a different key than the
getDivelog data. We have always compensated for that by looking up the
correct key and applying the data to that dive, but unfortunately we
didn't adjust the loop to correctly retrieve the getDive data for the
dives that were downloaded. So depending on how big the offset between
those two keys was we wouldn't get all of the necessary data.
With this change we try one, calculate the offset and then restart the
loop. Insane, but appears to be the only way to make this work.

Mostly coding style and whitespace changes plus making lots of functions
static that have no need to be extern. This also helped find a bit of code

This moves the fields 'duration', 'surfacetime', 'maxdepth',
'meandepth', 'airtemp', 'watertemp', 'salinity' and 'surface_pressure'
to the per-divecomputer data structure. They are filled in by the dive
computer, and normally not edited.
NOTE! All actual *use* of this data was then changed from dive->field to
dive->dc.field programmatically with a shell-script and sed, and the
result then edited for details. So while the XML save and restore code
has been updated, all the displaying etc will currently always just show
the first dive computer entry.

Since multiple dives can reference the same divesite we need to do the

This actually makes us internally use 'micro-degrees' for latitude and

The initial downloader reused the XML parsing of SDA files that was
implemented early in order to support the information extracted from the
SDA with the java applet. But creating this intermediary XML file and
handing it off to the XML import function always seemed like an ugly way
to do things. This became even more obvious when adding more features to
the Uemis downloader.
This commit completely changes the downloader to instead create dives and
record them directly.
This also adds support for divespots (which are stored in a seperate
database that needs to be queried after the divelog and dive entries have
been combined - the Uemis firmware clearly was written by monkeys on
crack - oh wait: I'm trusting these same people to get the deco right?).
This commit leaves the SDA import capability in the XML parser intact.
I'll remove that later. Because of this it actually adds a few lines of
code, but the overall change will be a substantial code deletion.

Actually, it's even better than that. Thanks to the new divecomputer
datastructure we can now simply look up in the dive_table which dives have
been downloaded from this specific Uemis SDA.
This patch removes the old gconf based code - which leads to one
unfortunate problem: the first time a Uemis SDA owner runs this version of
Subsurface against their data file ALL dives will be downloaded again
(which may not be a bad thing as we have improved a few other details of
Uemis support so now they get their deco information, surface pressure and
other data that we have started to support since 2.1). Still, this is not
ideal. But I didn't want to keep the legacy code around since this new
solution is so much cleaner.

The code pretended to support this for libdivecomputer based downloads,
but it had never been hooked up when the native Uemis downloader was
implemented. When I finally decided to close that feature gap I realized
that the original code was, shall we say, "aspirational" or "completely
bogus" and therefore never worked.
So instead of just hooking up the code for the Uemis downloader I instead
implemented this correctly for the first time for both libdivecomputer and
the native Uemis downloader.
In order not to have to mess with multithreaded Gtk development I simply
opted for a helper function that fires on a 100ms timeout and have it end
the dialog without a response. This way we can run the dialog while
waiting for the download to finish, still update the progress bar and
respond in a useful manner to the user clicking cancel.

And again buffer_insert contained the blatant bug.
The code wasn't copying the trailing '\0' when extending the string, which
usually didn't end up blowing up the code (and therefore kept the bug
hidden until now) because of the way realloc reused memory - we just had
trailing garbage strings. But sometimes we weren't so lucky and the strlen
in a subsequent call of buffer_insert would run past the end of the
allocated buffer.
Oops.

Start every step with much longer timeouts (until we get the first
response back), but then use shorter timeouts once we have started
receiving data.
This uses up fewer of the ANS files and allows us to get more dives
downloaded before the SDA has to be unplugged to reset communications,
yet at the same time it still improves the overall download time.

This will hopefully not be something we need often, but if we improve
support for a divecomputer (either in libdivecomputer or in our native
Uemis code or even in the way we handle (and potentially discard) events),
then it is extremely useful to be able to say "re-download things
from the divecomputer and for things that were not edited in Subsurface,
don't try to merge the data (which gives BAD results if for example you
fixed a bug in the depth calculation in libdivecomputer) but instead
simply take the samples, the events and some of the other unedited data
straight from the download".
This commit implements just that - a "force download" checkbox in the
download dialog that makes us reimport all dives from the dive computer,
even the ones we already have, and an "always prefer downloaded dive"
checkbox that then tells Subsurface not to merge but simply to take the
data from the downloaded dive - without overwriting the things we have
already edited in Subsurface (like location, buddy, equipment, etc).
This, as a precaution, refuses to merge dives that don't have identical
start times. So if you have edited the date / time of a dive or if you
have previously merged your dive with a different dive computer (and
therefore modified samples and events) you are out of luck.

When the user closes the divelist and starts with an empty file it makes

With this commit we not only use the getDivelogs command but also the
getDive command for each of the dives that was downloaded. Oddly, that
makes quite a bit of redundant (and at times slightly contradictory) data
available, but also many new things.
We now get weight, suit and notes that were stored with a dive in the
logbook on the divecomputer. There are a ton more data available that we
don't use, yet. For example information about altitude, a decoindex, dive
type and dive activity, other equipment information, etc.
I still need to decide how much of this I want to make available in
Subsurface (and how I want to present this - after all most of this is not
available from other dive computers).

Add a very rough first German localization so I can at least test what I
have done. Seriously, I have never used a localized OS, so I am certain
that I have many of the 'standard' translations wrong. Someone please take
over :-)
Major issues with this:
- right now it hardcodes the search path for the message catalog to be
./locale - that's of course bogus, but it works well while doing initial
testing. Once the tooling support is there we just should use the OS
default.
- even though de_DE defaults to ISO-8859-15 (or ISO-8859-1 - the internets
can't seem to agree) I went with UTF-8 as that is what Gtk appears to
want to use internally. ISO-8859-15 encoded .mo files create funny
looking artefacts instead of Umlaute.
- no support at all in the Makefile - I was hoping someone with more
experience in how to best set this up would contribute a good set of
Makefile rules - likely this will help fix the first issue in that it
will also install the .mo file(s) in the correct place(s)
For now simply run
msgfmt -c -o subsurface.mo deutsch.po
to create the subsurface.mo file and then move it to
./locale/de_DE.UTF-8/LC_MESSAGES/subsurface.mo
If you make changes to the sources and need to add new strings to be
translated, this is what seems to work (again, should be tooled through
the Makefile):
xgettext -o subsurface-new.pot -s -k_ -kN_ --add-comments="++GETTEXT" *.c
msgmerge -s -U po/deutsch.po subsurface-new.pot
If you do this PLEASE do one commit that just has the new msgid as
changes in line numbers create a TON of diff-noise. Do changes to
translations in a SEPARATE commit.

It builds on Windows :-)
